VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 314,404?, dated March2li, 1885.

Applicaiion filed May 8,1884. (No model.)

To all. whom t may concern: i

Be it known that I, J. BENNETT WALLACE, of Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Hydrocarbon -Vapor- Generating Burners; and I doherebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings', and to theletters of reference marked thereon, which forni a part of thisspecification.

This invention relates to hydrocarbon-vaporgenerating burners having aninduction-pipe, and more particularly to devices in such burners for attimes deilecting the current of vapor to the exterior of the burner,whereby the iiame of such vapor may keep the generatingpassages heatedwhen the burner is not in active use.

The invention consists in certain novel features of construction,hereinafter fully set forth, and pointed out in the claims.

In the drawings, Figures l to 5, inclusive, show the improvement appliedto a burner having its induction-tube inclined with reference to thebase of the burner proper. Fig. l is a front elevation. Fig. 2 is asection in the vplane of line .fr .fr of Fig. l, showing a sideelevation of the inductiontube and needle-valve tube. Fig. 3 is a top orplan view with burner-cap removed, and a principal part of the burnerbase-plate broken away. y Fig. fi is an indirect section in the line yg/ of Fig. 2, but vertical through the ascending liquid-tube of Fig. l.Fig. 5 is a transverse section of the induction-tube and deflector inthe line e e of Fig. 4. Figs. 6 to l0, inclusive, show theinventionlapplied to a burner having a curved induction-tube. Fig. 6 isa perspective view of such a burner. Fig. 7 is a plan or top viewshowinggthe burner-cap removed and a portion of the burner base-plateremoved. Fig. 8 is a vertical section in the plane of a; rc, Fig. 7,showing the induction-tube, the deilector, and the needle-valve tube inside elevation. Fig. 9 is a section in the indirect line y y of Fig. 8.Fig. l0 is a transverse section of the induction-tube and deiicctor inthe line z z of Fig. 8. Fig. 10a shows in end view a modified form ofthe deiiector. Figs. l1 and 12 show the improvement applied to a burnerhaving a vertical induction-tube. Fig. 1l is a front elevation, and Fig.12 is a central vertical section.

The same letter is applied to the same part in all figures of thedrawings.

The style of burner here shown is that in which a perforated cap isemployed in counection with a base-plate which supports theinduction-tube. The invention is, however, applicable to burners inwhich the inductiontube is otherwise upheld.

The invention contemplates thc presence of liquid-conveying pipes, or ofa body of inet-al connecting with such pipes in the neighborhoodthereof, against which thevapor-ame may be deflected for the purpose ofkeeping the generating parts hot while the burner is disused.

In the present drawings, A isa burner baseplate. B is a pipe conveyingliquid into contact with parts heated by the burner-flame. C is al pipecommunicating with the pipe B at its top. D is a lateral branch of thepipe C. D is a tubular projection of the pipe D, ar-

tube of the burner. E is thc shaft or stem of the needle-valvescrew-threaded into the projection D. E is thepoint of the needle-valve,seen protruding through the ejection-orifice ofthe tube D. F istheinduction-tube ofthe burner. G is the deiiector, and G is the handleor lever bywhich the deflector is moved from one of its positions to theother. i

The distinctive feature of my improvement is found in the constructionof the inductiontube with a longitudinal slot in one side thereof and amovable part fitted to the slot,which in one position partially formsthe wall of the induction-tube, and in another position it partiallyoccupies the passage of said tube, and

the burner.

As the best means of securing` the desired movement of the deiiector,and of giving the proper direction to the vapor when the latter isdeflected thereby, said deiiector is preferably pivoted (usually at ornear its upper end) to the induction-tube or to an adjacent part of theburner.

In the drawings the deflcctor is shown as ranged in the prolonged axisof the inductionoperates as a deflector by which the vapor and flame aredirected upon exterior parts of ICG tubular, but it may, if preferred,be partitubular, or trough-shaped, as shown in Fig. a. It is constructedto ll the slot or cutaway portion of the induction tube when thrownoutof use, and is preferably shaped in its inner surface to conform tothe circular interior curve of the induction-tube, as indicated in Figs.5 and 10. Said deiector, as will be observed, is limited in itsmovement, so that when its lower or outer end is thrown inward its mouthor opening will be in posi- -tion opposite the needle-valve opening, and

will thus perfectly intercept the vapor that would otherwise enter theinduction tube, while the upper or inner end is in position to directthe vapor or iiame against the proper parts to be heated.- The inwardswinging movement of the deflector may iind its natural andproperlimiting-stop inthe coniormation of the tubes. the free end of thedeflector strikingy against the opposite wall of the induction-tube. Theouter movement may be arrested by different means or stops in differentcases.

In Figs. 1 to 4, for example, the upper end 0I" the deiiector isprovided with a projection, g3, which strikes an opposing stationarysurface when the inner surface of said deiiector comes flush with theinner surface of the induction-pipe.

. f In Figs. 6 to 9 the prolongation of the delector beyond the pivot gserves the saine pury pose, while in Figs. 11 and 12 the lower or freeendofthe deflector strikes a neighboring stationary part. The projectiong3 in Figs. 1 to 4 also serves the purpose of deflecting the vapor loriiame more directly against the parts through which the vapor or liquidpasses to the needle-valve, and which, as will be seen in all thefigures, are generally proximate to the said deiiector.

lits throw.

In Figs. 6 to 10 the same condition as to the inclination and frictionlast referred to obtain,

and as a further provision for retaining the deiector the lever G (whichis in a degree elastic and is rigidly attached to the deector) isarranged to bear upon the transverse or horizontal branch tube D.

In Figs. 11 and 12 the deflector is provided with a downward projection,G2, which bears closelyT against a longitudinal lateral rib7 d, on theside of the tube D, with sufficient friction to hold the defiector inits advanced position.

The delector is used not only to detlect the vapor and give a iiamebeneath the burner, but also to deiiect the stream of liquid forinitially heating the burner, when this method of such heating isemployed.- The drip-cup II may be'accordingly arranged in position tocatch the liquid that will fall from the parts upon which it isdirected, as shown in Figs. 11' and 12.

It is to be understood that I do not broadly claim devices whereby thevapor may be directed either within the burner or toward exterior partsof the burner, as such devices in various forms are well known.

I claim as my inventionl. The combination, with `a longitudinally-.-slotted induction-tube, adjacent parts to beV heated, and a valve forthe ejection of vapor,z ofa defiector movably mounted in the slotof theind action-tube, substantially as described.

2. The combination, with a longitudinally-l` slotted indnction-tube, avalve for the emis-` sion `of vapor, and vapor-generating parts, ofamovable deflector iitted to the slot of the induction-tube, and havingVits inner surface l shaped to conform to the stationary wall of the,

said tube, substantially as described.

3. The combination, with a longitudinallyslotted induction-tube, a valvefor ejection of vapor, and Vapor-generating parts, of a delector fittedto the slot of the induct-ion-tube, and pivoted at its end adjacent tothe burner, and a lever attached to the deflector, substantially asdescribed.

4. The combination, with a longitudinallyslotted induction-tube of avapor-generating burner, of a pivoteddeiiector fitted to the slot,

and a stop constructed to arrest the defiector in position to form apart of the wall of the induction-tube, substantially as described.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.
